DatabaseOracle::insert	(	$table,
		$a,
		$fname = `__METHOD__`,
		$options = `[]`
	)

INSERT wrapper, inserts an array into a table.

$a may be either:

A single associative array. The array keys are the field names, and the values are the values to insert. The values are treated as data and will be quoted appropriately. If NULL is inserted, this will be converted to a database NULL.
An array with numeric keys, holding a list of associative arrays. This causes a multi-row INSERT on DBMSs that support it. The keys in each subarray must be identical to each other, and in the same order.

Usually throws a DBQueryError on failure. If errors are explicitly ignored, returns success.

$options is an array of options, with boolean options encoded as values with numeric keys, in the same style as $options in IDatabase::select(). Supported options are:

IGNORE: Boolean: if present, duplicate key errors are ignored, and any rows which cause duplicate key errors are not inserted. It's possible to determine how many rows were successfully inserted using IDatabase::affectedRows().

Parameters

string	$table	Table name. This will be passed through DatabaseBase::tableName().
array	$a	Array of rows to insert
string	$fname	Calling function name (use METHOD) for logs/profiling
array	$options	Array of options

DatabaseOracle::upsert	(		$table,
		array	$rows,
		array	$uniqueIndexes,
		array	$set,
			$fname = `__METHOD__`
	)

INSERT ON DUPLICATE KEY UPDATE wrapper, upserts an array into a table.

This updates any conflicting rows (according to the unique indexes) using the provided SET clause and inserts any remaining (non-conflicted) rows.

$rows may be either:

A single associative array. The array keys are the field names, and the values are the values to insert. The values are treated as data and will be quoted appropriately. If NULL is inserted, this will be converted to a database NULL.
An array with numeric keys, holding a list of associative arrays. This causes a multi-row INSERT on DBMSs that support it. The keys in each subarray must be identical to each other, and in the same order.

It may be more efficient to leave off unique indexes which are unlikely to collide. However if you do this, you run the risk of encountering errors which wouldn't have occurred in MySQL.

Usually throws a DBQueryError on failure. If errors are explicitly ignored, returns success.

Since: 1.22

Parameters

string	$table	Table name. This will be passed through DatabaseBase::tableName().
array	$rows	A single row or list of rows to insert
array	$uniqueIndexes	List of single field names or field name tuples
array	$set	An array of values to SET. For each array element, the key gives the field name, and the value gives the data to set that field to. The data will be quoted by IDatabase::addQuotes().
string	$fname	Calling function name (use METHOD) for logs/profiling
